Decoration must see: several commonly used white pigment
(1) titanium dioxide: also known as titanium dioxide, is used in inks, coatings, plastics, the main white varieties.
Zinc Oxide: Zinc Oxide (2) also known as zinc, zinc oxide, molecular formula ZnO, the melting point of 1720 DEG C, the refractive index of 1.92-2.00. Zinc Oxide is commonly used in rubber coloring, but also for plastic coloring, such as ABS, polystyrene.
(3): also known as lithopone lithopone lithopone, is a mixture of zinc sulfide and barium sulfate, which molecular formula can be written as ZnS+BaSO4. The content of zinc sulfide is 15, 30, 40, 50 and so on. Barium zinc white can be used to make a good white, its coverage is relatively strong, between Zinc Oxide and titanium dioxide. But because of the superior performance of titanium dioxide is widely used in plastic colouring, lithopone application is very limited.
